COMBINED PUNcir AND SETTING-MACHINE.

To all whom it may concern Be it known that. I, EDWIN BALL STIMr- SON, a citizen of the United States, residing at Brooklyn, in the count-y of Kings and State of New York, have invented certain new and useful Improvements in Combined Punches and Setting-Machines, of which the following is a specification.

Y This invention relates to combined punching and setting machines and has special refholes in leather or the like and automatlcally setting eyelets or other fastening devices in the punched out holes. M

The principal object of the invention is to improve and simplify the general construction of devices of this character.

With the above and other objects in view, the invention consists in general, of certain novel features of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

In these drawings, Figure 1 is a front elevation of the machine with the bottom portion of the pillar broken off; Fig. 2 is a vertical longitudinal section on the line 22 in Fig. 1 looking in the direction of the arrows; Fig. 3 is a side elevation of the machine looked at from the reverse side of Fig. 2; Fig. -1 is a'horizontal section partly in plan on the line 4-4 in Fig. 2; Fig. 5 is a vertical section on an enlarged scale on the line 5-5 in Fig.4 looking in the directionof the arrows; Figs. 6 and 7 respectively are horizontal sections on the lines 66 and 7-7 in Fig. 2; Fig. 8 is a perspective view on an enlarged scale of the plungers and of the punch and eyeleting spindle which they support; Fig. 9 is an enlarged detail view of the eyeleting spindle and the lower portion of the upper set in Fig. 2.

I will now describe the devices 7 of the drawings, reserving it to the claims to point out the novel features and to define the scope of the invention, it being understood that .the claims will be given the due range of equivalents to which they may be entitled in View of the art. 1

The frame of the machine comprises a pillar 1, a bifurcated head with horizontally extending arms 2 and 3, the casting for said head consisting of two vertical sides 4 and 5 (Figs, 1 and 2) joined by an integral web 6 shown in vertical section in Fig. 2.

Serial No. 658,984

:2 is a vertically reciprocating eyeleting spindle which picks the eyelets from the end of a roadway 8 that delivers the eyelets from the magazine 9, said magazine and roadway pivoting about the pin 10.

11 is-a vertically reciprocating punch in back of but independent of the eyeleting spindle 7.

12 is a die mounted in alinement with the punch and in the end of the arm 2 (Fig. 2).

13 is a Work-supporting table which reciprocates horizontally in fore and aft direction looking at the front of the machine as m Fig. 2, or reciprocates from left to right, and vice versa, in Fig. 2. This table rolls on ball bearings 14 running in sockets 15111 the tops of the vertical arms of a fork 16 bolted at 17 to the front of the pillar 1. The table 13 is prevented from lifting off the arms 16 as it slides thereon by screws 18, two on a side, the heads of the two front screws being covered by plates 19 to prevent the operators-fingers from getting caught in the slots 20 in the table which, it will be noted, slides relatively to the screws 18 which are fixed. These slots 20 consist of a widened upper portion a (Figs. 4 and 5) slidably receiving theheads c of the screws; and further consists of narrow portions 1) slidably receiving the unthreaded shank portions (Z of the screws. The above described protective or cover plates are themselves lo.-

(rated in recesses in the top of the table 13...

to be flush therewith and are secured in that position by screws 21 (Figs. 4 and 5).

.The eyeleting spindle 7 is telescopically supported in a cylindrical recess in the upper set 22 (Figs. 2 and 9) and has a head 7 engaging the top ofthe contracted lower portion of said recess to prevent the spindle 7 on the end of the spindle 7 separated by the shoulder 7 from the upper portion of eyelets are set, to work up into the space between the inside of the socket in the set 22 and the spindle 7 and thereby to make the spindle stick in its socket. This happens even when the spindle tapers to its ihe tendency is for the hut and particles from the material wherein the extremity,but in my improvement the shoulder 7 as it slides in the socketkeeps it clean and clear. The upper end of the set 22 is fixed in a socket in the bottom of the plunger'24 (Figs. 1, 2, 7 and 8), Fig. 8 showing the plunger and related parts in perspective detached from the machine. The plunger reciprocates vertically in suitable guides G (Figs. 2 and 6) supported on the sides 4 and on the upper arm 3 of the head of the machine, the inner faces of said sides themselves likewise acting as guides for the sides of the'plunger. The plunger has a bifurcated upper end 24 across which aIpin-25' (Fig. 2) extends that pivota'lly connects the lower toggle arm 26 'to the plunger. The free end of the upper toggle arm 27 4 is connected with a trunnion pin 28 (Figs-1 and 2) supported across the space between the sides 4 and 5 of the upper arm 3 of the machine head.

' 292is the 'connectingrod which operates the toggle arms,fsaid,rod at its other end being connected'withthe crank pin 30 on a cam disk 31 that rotates with the drive shaft '32 and drive pulley 33. This completes the description of the mechanism for reciprocating: the eyeleting spindle.

I will next-describe the means for reciprocating the punch-ll-which is 'fixedin the lower end of a plunger 34' (Figs.2-and 8.). This plunger 34 slides vertically between the sides of a recess 24" (Figs. 8, 6, 7 and 2) in plunger 24."

35 (Fig: 2) is an elbow lever pivotally supported on a pin 36 extending across between't-he sides 4 and 50f the upper arm of the machine head. This lever has a horizontal, arm whoserounded end extends into a socket in the upper end of plunger-34 and whose upright arm is normally drawn back to cause the elbow lever to lift the punch by a spring 37 (Figs. 2 and-3) attached to ohnedside 4 of the upper arm of the machine ea a 38 is a connecting rod between the upright arm'of this elbow lever 35 and thedepending arm of anotherelb'ow lever 39 (Figs. 2 and 3) pivotally supported on a pin 40 extending acrossbetween the sides 4 and 5 of the upper arm of the machine head at the rear thereof. The upper or horizontal arm (shown in Fig.3) of this last named elbow lever 39 has a horizontal stud 39 supporting a roller 41 which bears peripherally on the cam disk 42 which is circular except for the single sharp projection shown, and is kept thus bearing against said cam by the spring 37. The diameter of the circular portion of the cam disk 42 is such that it permits the spring 37 to keep the punch plunger 34 raised for nearly a complete rotation of the cam disk and until its projection is reached, whereupon through the described elbow lever 39 and its connections with the punch plunger 34, it is quickly forced down to punch the hole in the article and is as quickly lifted by the spring 37 after the pro ection on the cam disk has ridden past the roller 41 (Fig.3).

I will now describe the means for reciprocating the work-supporting table 13 :46 is a bell crank lever pivoting on a stationary pin 47 (Figs. 2 and 3) and having the end of its verticall depending arm connected with the rear 0 the table 13 by a link 48 and having the end of its horizontal arm connected by a vertical link 49 (Figs. 2 and 3) with the lever 45 (Fig.2) whose other end is pivotally supported on the pin 40.

50 is a roller on a horizontal stud supported on the up er side of this lever 45 to bear peripheral y on a cam disk 44 which is fixed alongside the other cam disk 42 on the same drive shaft 32 This cam disk 44.

(Fig.2) has'a circular portion and a portion of reduced radius leading to said circular portion ofgreater radius.

51 is a tension spring connecting the horizontal arm of the bell crank lever 46 with a pin projecting froma part of the machine head above said arm, said spring thereby normally holding the table 13 drawn back into its rearmost position with the roller 50 in' contact with its cam disk. This is the position of theytable as long as the roller 50 is in contact with the 'ing the reduced radlus which is nearly oneportion of the camhavhalf-the diameter of the cam disk; but as.

soon as the larger portion of the disk rides around I into contact with the roller; its greater radius forces down the lever 45 and through the described connections pushes the table 13 into its forward position and holds -it there for somewhat over one-half the given rotation of the cam disk 44.

It will be noted how the above described operating means for the table, punch and eyeleting spindle respectively constitute means for operating said parts in timed re-.

lation because the cam disks 44 and 42 and the crank pin 30 controlling the operation of these parts are all carried around together in definite relation to one another. Thus, re-' ferrin'g to Fig. 2, the projection of the cam disk- 42 is just about to ride pastv the roller 50 to operate the punch 11. At this time it will be seen that the small radius of the other cam disk 44 is riding on its roller 41 and continues so to do after the punch 11 has completed its stroke and is in up position clear of the article,-which means that .during this time the table '13 is maintained at rest, as it should be,'to permit the punching operation to take place. As the cam disks continue on their rotation, the larger radius of the disk 44 is soonreached and-the table 13 is pushed forward a distance calculated to be exactly equal to the distance between the punch and theeyeleting spindle, with the result that the'punched hole in the article is brought directly under the eyeleting spindle 7 and is kept there for the interval that the larger radius of the cam 44 keeps the lever 45 depressed (Fig. 2). Meanwhile, the crank pin 30 is rotating with the cam disks toward its forward position directly across from its shown position in Fig. 2, and is moving the eyelet-ing spindle 7 downwardly to enter the eyelet-held in the end of the roadway 8, then to pick saideyelet out of the roadway. by reason of the roller 53 on the plunger 24: forcing the roadway to the right in Fig. 1 by hearing against the cam face 5% on the roadway, and finally to carry the eyelet on the spindle 7 down through the punched-out hole in t e art c e and to clench it therein by the bottom of the upper set 22 forcing the body of the eyelet against the lower set ,55 (Fig. 2) to spread and clench it, the spindle 7 meantime telescoping upwardly into itssocket in the upper set. This eyelet, or other form of fastener, setting stroke of the machine is completed when the crank pin 30 is in its above assumed right-hand position in Fig. 2. As it rotates back to its shown lefthand position in that figure, it initiates and completes the up stroke of the eyeleting means.

It may here be noted in passing that when the plunger 24 on its down stroke cams back the roadway 8 (Fig. 1) as above describedfi the latch 56 drawn down by the spring 57 looks the roadway in cammed back position by the notch in the end of the latch engaging the pin 57 in the roadway. The latch is raised near the end of the up stroke of the plunger 2 L by the pin 58 (Fig. 1) on the plunger contacting therewith, whereupon the tension spring 59 returns the roadway to its normal position shown in Fig. 1 preparatory to feeding an eyelet to the eyeleting means on its next down stroke. Meanwhile, by the described up stroke of the eyelet-ing means the smaller radius of the cam disk 44 has again reached the roller 50 and has permitted the table 13 to be drawn back preparatory to the next down stroke of the punch.

To adapt the machine for accurately positioning the eyelets in a lot of calendars or other articles of uniform shape, I have devised a work-positioning gage 60' (Fig. 4:)- which preferably extends transversely across the table 13 as shown in that figure.

61 and 62 designate set screw and slot connections between the gage and the table permitting the former to be fixed in a range of fore and aft positions on the table.

63 is an arm projecting forwardly at right angles from the gage and having a setscrew 64 and slot 65 connection therewith permitting the arm to be adjusted bodily along the gage. The articles to be punched and eyeleted are positioned one at a time on the table by fitting the given corner of each in the angleformed betweenthe front edge of the gage 60 andthe side of the arm 63, these latter being adjustable relative to each other and'the gage being adjustable in position on the table 13. to position the eyelet at exactly the desired location in the article.

The front portion of the gage 60 is .cut away at 60 so that it will not strike the presser foot or stripper 66 (Fig. :2) secured to the depending portion of the machine head. It may be noted in passing that, of course, the gage 60 is shown in Fig. 4 as having a position which is too far forward for any working position which it will ever receive, because in the position there shown the article would not be punched at all because the punch is in vertical alinement over the die and the gage will be seen to prevent the article from being under the punch.

It is unnecessary to describe the details of the magazine 9, its relation to the roadway, its suspension from the axis 10, and the mechanism by which it is operated from the oscillating arm 70 on the end of the trunnion pin 28 of the upper toggle arm 27, because these parts are substantially the same as those set forth and described in my copending application for improvements. in setting machines, Serial No. 640,499.

71 (Fig. 2) is a rod connected below with the treadle of the machine, which latter, however, is not shown. Above, this rod connects with a well lmown form of clutch 100 mechanism whereby the drive pulley 33 merely turns idly without rotating the cam disks to operate the machine, so long as the treadle is not operated.

The particular machine shown in the drawings is a combined punching and eyeleting machine but of course other forms of fastener setting means may be substituted for the eyeleting means, such as means for setting rivets, etc.

Having thus described my invention, what I claim is: j i

1. In a combined hole-punching and setting machine, the combination of vertically reciprocating punch means, vertically. I'eciprocating setting means, a horizontally reciprocating Work-support which carries the work from the punch means to the setting means so that the holes punched by the punch means are in alinement with the setting means, a crank and means for operating all of the aforesaid means in timed relation, wherein the work-support is moved to the setting means after the punch means'has cooperating with the cam and itself operatively connected with the setting means, a second cam carried around with said crank, and cam lever means cooperating with said second 'cam and being operatively connected with the work-support.

2. In a combined hole-punching and setting machine, the c'omomation of settingmeans comprising a suitably guided vertically reciprocating plunger carrying a setting spindle, punch means comprislng another e vertically guided to reciprocate in a recess in the first named plunger, ahorizontally reciprocating reciprocating plunger work-support which carries the work from the punch means to the set-tingmeans so that the holes punched by the unch means are in alinement with the spindle of the setting means, and means for operating all of the aforesaid means in. timed relation, wherein the work-support is moved to the setting means after the punch means has been operated and before the setting means is operated.

In testimon whereof I afiix my signature 25 0 two witnesses. EDWIN BALL STIMPSON. Witnesses:
